+1 on all of that and even using weather and darkness as an excuse not to get outside is a cop out, given modern equipment.
For me the challenges of Autumn and winter make for the best, most rewarding and memorable outdoor exploits.
That also includes winter camping nothing finer than waking at sunrise on the hill (or anywhere quite for that matter} with a covering of snow and ice and lingering over a brew and breakfast, ok it may be raining but that just means you cut out the linger and get in a few more miles, win win in my book.
A great time of year for Bikepacking if injury says shanks pony is out.
Even the extra cleaning an care of the kit is a labour of love.
